Phelps finished third in the 200-meter individual medley Sunday, and Missy Franklin won the 100 backstroke.

Phelps led the through the first three laps, before tiring to finish in 1 minute, 59.76 seconds. Olympic gold medalist Conor Dwyer won in 1:59.49, and Chase Kalisz was second in 1:59.53.

“It’s a pretty credible swim,” Bowman said. “He hasn’t done much training and to be under two minutes is very good.”

It was his fourth event in three days. He swam in two events in each of his first two meets since returning to competition. Phelps was second in the 100 free and 200 free and tied for first in the 100 butterfly.

“It lets us know exactly what we need to work on,” Bowman said. “He needs to have endurance. He’s only going to get better.”
